Pygame - scroll down the page

My program in a nutshell is a Contacts application, which obviously means that a person should be able to store several contacts in the application, which, in turn, means that the contacts will eventually be turned off on the screen, so I need to scroll down the page so that a person can see all his contacts and interact with a specific contact.

However, I have a little pickle ... how do I do this? The problems I am facing is that the application has a fixed width and height, so I can not scroll down the page to find that the background will be black, because my rectangle was only sized as long as the application window length. Another problem is that I just don’t know how to “tap” the screen. I just have no idea.

Here is the program code:

import pickle
import operator
import pygame
import sys
from pygame.locals import *
from itertools import groupby

#create Contact class
class Contact():
    def __init__(self, firstName, lastName, address, groupType,
                 telephone, mobile, email, photoField):
        self.firstName = firstName
        self.lastName = lastName
        self.address = address
        self.groupType = groupType
        self.telephone = telephone
        self.mobile = mobile
        self.email = email
        self.photoField = photoField

    def showDetails(self):
        print("First Name:\t", self.firstName)
        print("Last Name:\t", self.lastName)
        print("Address:\t", self.address)
        print("Telephone:\t", self.telephone)
        print("Mobile:\t", self.mobile)
        print("Email:\t", self.email)

    @classmethod
    def from_input(cls):
        firstName = input("First Name: ")
        lastName = input("Last Name: ")
        address = input("Address: ")
        telephone = input("Telephone: ")
        mobile = input("Mobile: ")
        email = input("Email: ")
        return cls(firstName, lastName, address, None,

                   telephone, mobile, email, None)

I apologize for the mix of pygame code and python source code, since I still have not completely converted the shell code into code that pygame can use. So contacts, etc. Still running through console / console. First I want to finish the main screen before I get to actually passing input through pygame.
